Dependent claims

A plaster type interior textured coating remover composition in the form of an aqueous solution comprising

(A) at least one alkoxy ether solvent in an amount which does not exceed 90% by weight, based on the weight of the composition;

wherein R1 is H or group of the formula
where R3 is a straight or branched chain 6-22 C alkyl or alkenyl group;
R2 is H, or methyl or ethyl;
w is 1 or 2;
and Q1 is —COOM1 or —SO3M1, in which M1 is an alkali metal cation or an optionally substituted ammonium group;

R5 is a straight or branched chain 6-22 C alkyl or alkenyl group;
m is 0 or 1;
and each of x, y, and z is an integer wherein the total number of (CH2CH2O) groups is in the range of from 2 to 50;
(ii) an imidazoline compound of the formula III
wherein R is a straight or branched chain 7 to 18 C alkyl group and x is a number from 2 to 10;
(iii) a compound of the formula IV
in which R is a straight or branched chain 7-18 C alkyl group;
R1 is —CH2CH2OH or —(CH2)—x—COONa, where x is 1 or 2, R2 is (CH2)YCOONa, where y is 1 or 2;
and R3 is H or —CH2CH2OH;
and
(iv) an alkyl betaine of the formula V
R—N+(CH3)2CH2COO− (V)
wherein R is a straight or branched chain 7 to 18 C alkyl group;
and
(E) 0.1 to 20% by weight of a compound having the general formula VI
RZ(QO)nH (VI)
wherein R is a straight or branched chain 6-22 C alkyl or alkenyl or an alkylphenyl group;
Z is O or NH;
Q is —(CH2)2— or —(CH2)3— or a combination thereof;
n is such that the Hydrophilic Lipophilic Balance (HLB) of the molecule will be 7.3 to 15.0.
